GENERAL
Warning for Counterweight and Front
Attachment Removal
Before any attempt is made to begin removal or installation of
the counterweight, the excavator must be parked on a firm and
level supporting surface, with no sloping surfaces or soft or
muddy ground in the area where the assist lift crane will be
working. Position all accessories in the overnight storage
position.
Responsibility should be assigned to one person to be in charge
of the lifting crew, and to verify that required safe lifting
precautions have been taken before each part of this procedure
has been started.
All members of the working crew should know and understand
the signals that will be used between the lifting leader, the assist
crane operator and the remainder of the work crew.
